DESCRIPTION

The LM20323 is a full featured 500kHz synchronous buck regulator capable of delivering up to 3A of load

current. The current mode control loop is externally

compensated with only two components, offering both

high performance and ease of use. The device is

optimized to work over the input voltage range of

4.5V to 36V making it well suited for high voltage

systems.

The device features internal Over Voltage Protection

(OVP) and Over Current Protection (OCP) circuits for

increased system reliability. A precision Enable pin

and integrated UVLO allows the turn-on of the device

to be tightly controlled and sequenced. Startup inrush

currents are limited by both an internally fixed and

externally adjustable soft-start circuit. Fault detection

and supply sequencing are possible with the

integrated power good (PGOOD) circuit.
